The borosilicate glass bottle combines with polyester resin, polypropylene, and silicone components, and manufacture is in Japan. However, no replacement parts are sold, so damage to a component may mean replacing the complete brewer.

The brewer needs no separate brewing kit, but it still depends on coffee grounds, cold water, and access to a refrigerator. That makes the setup compact, though it is not independent of ordinary kitchen facilities.

The verdict

It is worth $34.50 USD for buyers who specifically want a dishwasher-safe, self-contained 650 ml glass brewer for refrigerated cold brew. The price covers a borosilicate glass bottle with an integrated polyester resin filter, polypropylene strainer, and silicone rubber spout and stopper. It needs no additional brewing kit, which keeps the required purchase focused on one cold brew accessory.

Pros

  • Self-contained: coffee, cold water and a fridge is the whole method, with the strainer built in
  • 650ml brewed, on Hario's own published ratio of 55g to about 700ml over 8 hours
  • Borosilicate glass, dishwasher safe, made in Japan

Cons

  • $34.50 above the $32.99 median
  • A glass bottle with resin and polypropylene fittings
  • Hario covers non-electric items for 90 days

What is the Hario Coffee Cold Brew Bottle?

The Hario bottle is a self-contained cold brew immersion brewer, one of the simplest coffee accessories for the method, combining a 650 ml borosilicate glass bottle with an integrated strainer.

Its brewing assembly includes a polyester resin filter and polypropylene strainer. A silicone rubber spout and stopper complete the listed material set, while the overall dimensions are 87 mm wide, 84 mm deep, and 300 mm high.

Made in Japan, it is designed around a bottle format rather than a collection of separate brewing pieces. Its listed price is $34.50 USD, placing one brewer, filter, strainer, spout, and stopper within a single accessory purchase.

Hario Coffee Cold Brew Bottle does it actually do its job?

Its specifications support the intended immersion setup, but they do not establish the quality or consistency of the coffee it produces.

The bottle uses borosilicate glass, while the filter, strainer, spout, and stopper use polyester resin, polypropylene, and silicone rubber respectively. Those named materials clarify what buyers receive, and the integrated strainer defines how grounds are separated within the brewer.

The 650 ml brewed volume gives a concrete output capacity, but capacity and materials cannot verify flavor, clarity, strength, or batch consistency. The absence of replacement parts also matters because a damaged component cannot be replaced through a listed parts program.

  • Borosilicate glass forms the bottle, with polymer and silicone components used for filtering, straining, pouring, and sealing.
  • The integrated strainer supports the brewer's stated immersion format without requiring a separate filtration accessory.
  • Its 650 ml figure describes brewed volume, not flavor quality, strength, clarity, or consistency.
  • The assembly is several distinct parts, so a breakage means checking with Hario before assuming the bottle is finished.

What you can brew with it

It is specified for cold brew coffee by immersion, with a 650 ml brewed volume and Hario's own recipe of 55 g of medium-fine coffee to about 700 ml of water, refrigerated for eight hours.

The supported use is straightforward: coffee grounds and cold water go into a self-contained brewer that is then placed in a refrigerator. The bottle format, integrated filter assembly, and stated brewed capacity define a focused cold brew setup rather than a multipurpose appliance.

Nothing in the listed specification supports espresso, hot brewing, milk preparation, grinding, or other drink formats. Buyers seeking those functions should choose equipment that explicitly includes them instead of treating this bottle as a broader coffee system.

  • It handles cold brew coffee through an immersion process using an integrated filter and strainer.
  • The stated 650 ml capacity refers to brewed volume within the bottle-based setup.
  • It requires grounds, cold water, and refrigeration, but no separate brewing equipment.
  • It is not specified as an espresso maker, grinder, hot brewer, or milk preparation tool.

Living with it, day to day

Day-to-day ownership centers on refrigerator space, dishwasher cleaning, and keeping the integrated filter, strainer, spout, and stopper together.

The brewer measures 87 by 84 by 300 mm, so owners can compare that footprint directly with their available refrigerator and cupboard space. Its listed weight and 650 ml brewed capacity provide additional planning details before purchase.

Dishwasher-safe construction removes the requirement to wash every listed component only by hand. Owners still need to manage the glass bottle, polyester resin filter, polypropylene strainer, and silicone pieces, and no replacement parts are available if one is damaged or lost.

  • Allow refrigerator space for a bottle measuring 87 mm wide, 84 mm deep, and 300 mm high.
  • Clean the dishwasher-safe bottle, filter, strainer, spout, and stopper after brewing as needed.
  • Keep the integrated components together because the assembly is several distinct parts.
  • Handle the borosilicate glass bottle with the consequence of full replacement in mind.

Hario Coffee Cold Brew Bottle vs OXO Cold Brew Coffee Maker

The Hario has documented capacity, materials, dimensions, and cleaning details, while an OXO choice requires checking those same facts before comparison.

For the Hario, buyers can verify a 650 ml brewed volume, dishwasher-safe construction, integrated strainer, and a self-contained setup requiring grounds, water, and refrigeration. Those details make its space, cleaning, and equipment requirements concrete before purchase.

Before choosing the OXO, check its current US price, brewed capacity, dimensions, materials, cleaning instructions, and need for extra equipment. Without those corresponding details here, no factual winner can be named on value, output, footprint, construction, or upkeep.

  • Hario wins on documented detail here, including 650 ml capacity, dimensions, materials, and dishwasher compatibility.
  • Hario suits buyers wanting a bottle-format immersion brewer with no separate brewing kit required.
  • OXO should be assessed using its official price, capacity, footprint, materials, and cleaning requirements before purchase.
  • Neither wins outright on value: the choice is bottle format against pitcher format rather than one spec beating another.

Is the Hario Coffee Cold Brew Bottle worth it?

It is worth $34.50 USD for buyers who specifically want a dishwasher-safe, self-contained 650 ml glass brewer for refrigerated cold brew.

The price covers a borosilicate glass bottle with an integrated polyester resin filter, polypropylene strainer, and silicone rubber spout and stopper. It needs no additional brewing kit, which keeps the required purchase focused on one cold brew accessory.

The value case is weaker for buyers who need replaceable components or want evidence comparing it with similarly priced alternatives. No listed replacement parts are sold, and there are no other priced accessories in the current set, so the $34.50 USD price lacks a direct benchmark.

Who should buy it (and who should not)

It suits buyers seeking a compact, self-contained cold brew bottle, but not those needing replaceable parts or broader coffee functions.

Choose it if a 650 ml brewed volume fits your needs and you have refrigerator space for its 300 mm height. The integrated filter and strainer also suit buyers who want to avoid purchasing a separate cold brew filtration kit.

Look elsewhere if you need espresso, hot brewing, grinding, or milk preparation from one product. It is also a poor fit when access to replacement components is essential, since no replacement parts are sold for the listed assembly.

Buy it if

  • You want one bottle-based accessory for refrigerated immersion brewing.
  • You need a stated 650 ml brewed capacity and dishwasher-safe components.
  • You prefer a setup that requires no separate brewing kit.

Skip it if

  • You need replacement filters, strainers, spouts, or stoppers to be sold separately.
  • You want espresso, hot brewing, grinding, or milk preparation functions.
  • You lack refrigerator space for a bottle standing 300 mm high.

Frequently Asked Questions

How much coffee does the Hario Coffee Cold Brew Bottle make?

The stated brewed volume is 650 ml. Hario's recipe is 55 g of medium-fine coffee to about 700 ml of water, refrigerated for eight hours, which is the ratio the bottle is built around rather than a required coffee-to-water ratio. Buyers can use 650 ml to judge whether one batch matches their household needs and whether the bottle offers enough output for their intended cold brew routine.

Is the Hario Coffee Cold Brew Bottle dishwasher safe?

Yes, the brewer is listed as dishwasher safe. Its components include a borosilicate glass bottle, polyester resin filter, polypropylene strainer, and silicone rubber spout and stopper. The specification does not require hand washing as the only cleaning method, though owners still need to keep track of each integrated component during cleaning and storage.

Does the Hario cold brew bottle need extra equipment?

No separate brewing kit is required. The self-contained setup needs coffee grounds, cold water, and access to a refrigerator. Its filter and strainer are integrated into the bottle system, so buyers do not need to add another filtration accessory. A grinder is not included among the listed functions, so the required input remains coffee grounds.

What are the Hario cold brew bottle dimensions?

The bottle measures 87 mm wide, 84 mm deep, and 300 mm high. Its stated brewed volume is 650 ml. Those measurements let buyers check refrigerator shelves, doors, and cupboards before ordering, without relying on a general description such as compact or space-saving.

Can the Hario cold brew bottle make espresso?

It is specified as a cold brew coffee immersion brewer with an integrated strainer, not as an espresso maker. Its listed use requires coffee grounds, cold water, and a refrigerator. Buyers who need espresso should choose equipment explicitly designed for that brewing method rather than expect this 650 ml bottle to provide an unlisted function.

Can you buy replacement parts for the Hario cold brew bottle?

Hario does not list replacement parts for this bottle, so treat the assembly as a unit. That matters because the assembly includes several distinct components: a glass bottle, polyester resin filter, polypropylene strainer, silicone rubber spout, and stopper. Buyers who prioritize long-term component replacement should account for the possibility that losing or damaging one part could require replacing the complete product.
